Yeah, I am not looking for the secret to anybody's color combo and I am not going to go into color production or anything like that. I'd just be happy to have more than 2 colors and I'd like to learn a little bit while I am at it. I looked in one of the mixing buckets while I was up there for 14 hours today and they aren't even going for the little chunks of cullet so I will make sure I pile up on the fritted cullet. Our directions are to add one spoon of cobalt to the bucket but everybody adds 2 spoon fulls and then lies to our teacher about what they are doing. I can't count the number of times people have asked where the spoon is. We have scales so I won't ask how many spoon fulls I need. There's only one person that mixes black and I haven't found out what he uses yet. He graduated but came back due to Hurricane Katrina but I haven't seen him to be able to ask him. I will keep notes and samples so hopefully I can get the results I am looking for eventually but there's not much that I could pull out of the pot that wouldn't make me happy. I know I am limited with the cullet but that's what I have access to for a while. I had a good idea while looking around the ceramics studio and decided to look for the pottery chemicals and found manganese dioxide and FeOxide black. It's the same instructor for both studios and he lets us do just about anything we want so I should be good there. I'll get what I don't have and I'll check out Dave's source too. I guess since I am back in school I feel like I should question things and this is something I have read about and followed on here but I had no way to try it. It has interested me for a while. Clean pots are probably necessary too so I need to buy a few small ones. I know there are lions, tigers, and bears along the yellow brick road but if it were easy it wouldn't be fun. Besides, it sure beats regular homework. I think you gave me enough to get started with listing what oxides give different colors for 7 pound batches. I don't know how many pounds they fit in the mixing buckets but 7 pounds sounds like a good place to start. Thanks Pete. I made my first encalmo bowl today and a teapot and the rest of the time I was just assisting one of the advanced students with different things but he doesn't know about the color stuff. It's kind of sad to me that not much is going on in the studio right now really but all I can do is just work to make it better. I wrote down what was written on the boxes that the stuff is stored in so I am going to list it in case what I need isn't really what I have. I probably have enough to get me in over my head in a hurry but I am willing to experiment and mix to see what I get. If nothing else I'll share my misery and we can all get a good laugh when things go horribly wrong. thanks for the help.

here's what I found that we had in the store room. I wrote down what was on the boxes it is all stored in. I know most of this is just for glazes and won't be used. We have stuff to melt batch too from what I found but I figured I woud list everything.:

red iron oxide
mang diox granular
mang diox 200 mesh
chrome oxide
FeOxide Black
CoOx cobalt oxide
NiCO2 nickel carbonate
FeCh Iron Chromate
CuCO3 copper carbonate
SnOx Tin Oxide
dr. Rutile
lt. Rutile
Illmenite gran.
Crocus Martis
Yellow Ochre
English China Clay
volcanic ash
soda ash
Tit Diox
bone ash
